Sounds like you’ve made up your mind already.
If you read these forums or talked to Continental/United pilots in the 2009-2013 time frame, a lot of the same concerns re: AA were present at UAL. Terrible management being at the center of all the issues. UAL’s stakeholders made the right decision to fire the moron Smisek, a new management team came in and turned things around drastically (and like Delta, hired an excellent PR team to convince you and remind you of their awesomeness).
The industry is cyclical. Isom et al can’t be in power forever. Hopefully.
